[Jython-users] String Object id question

[Robert W. B. <rb...@di...>]

Hi all,

I've ran into a bit of confusion with the id() of characters in
Jython compared with Python.  Here's something similar to the code
that started the confusion:

----------------------------------------------------------
S = "abc"
L = ["a", "b", "c"]
LoL = [L, L, L]
stringtest = S[1]
listtest = L[1]
loltest = LoL[1]

def test(obj1, obj2):
    if ( id(obj1) != id(obj2) ):
        return 0

assert(test(loltest, LoL[1])), "List-of-lists test failed"
assert(test(listtest, L[1])), "List test failed"
assert(test(stringtest, S[1])), "String test failed"
----------------------------------------------------------

In CPython, all passes, but in Jython, there's always an AE:
String test failed.  Is this expected? unavoidable?

Tnx
